Trevi Fountain (Italian: Fontana di Trevi) is a fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Pietro Bracci. Standing 86 ft high and 161.3 ft wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world. The fountain has appeared in several notable films, including Federico Fellini's La Dolce Vita, and is a popular tourist attraction. The backdrop for the fountain is the Palazzo Poli, given a new façade with a giant order of Corinthian pilasters that link the two main stories. Taming of the waters is the theme of the gigantic scheme that tumbles forward, mixing water and rockwork, and filling the small square. Tritons guide Oceanus' shell chariot, taming hippocamps.

In the centre a robustly-modelled triumphal arch is superimposed on the palazzo façade. The centre niche or exedra framing Oceanus has free-standing columns for maximal light and shade. In the niches flanking Oceanus, Abundance spills water from her urn and Salubrity holds a cup from which a snake drinks. Above, bas reliefs illustrate the Roman origin of the aqueducts.

The tritons and horses provide symmetrical balance, with the maximum contrast in their mood and poses (by 1730, rococo was already in full bloom in France and Germany).
